EDVARD SAIWIUEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO WILLIAM VHARTON, JR., 85 CO., (LIMITED) OF SAME PLAGE.

RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 335,484, dated February 2, 1886.

Application tiled December 19, 1885. Serial No. 186,181. (No model.)

To @ZZ whom, t may concern.:

Be it known that I, EDWARD SAMUEL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Railway-Switches, of which the following is a specification.

My invention relates to improvements inthe construction of that class of street-railway switches which are operated by the weight of the draft-animals attached to the cars as they pass over the movable platforms connected with the movable Switchpoint; and the object of my invention is to so construct the device as to facilitate the operation of the switch. This object I attain by combining with the switcli-tongue and movable plates hydraulic mechanism for transmitting the motion.

In the accompanying` drawings, Figure l is a plan view of part of the track, showing my improved switch mechanism; Fig. 2, a transverse section on the line l 2, Fig. l; Fig. 3, a section on the line 3 4, Fig. l, and Fig. 4, a section on the line 5 6, Fig. l.

A A are the switch-castings connecting the main and side tracks, the casting A being provided With the pivoted movable tongue (d, as shown in Fig. l.

B is a box, preferably made of cast-iron, to contain the operative parts of the switch. This box is below the level of the road bed, and is cut out for the reception of the switchcastings.

E E are two platforms or plates, on which the draft-animals tread as they pass over the switch. Directly under these plates E E are two hydraulic cylinders, D D, as shown in Fig. 2. The plungers F F of these cylinders are firmly secured to the plates E E, respectively. The cylinders are provided with the usual double packing-glands, cl d. Projecting downward from the switch-point a is a pin, a', which is secured to a block, z', connected on opposite sides to the piston-rods h h', of two pistons, h2, in the small cylinders H H, Fig. 3. These cylinders aresecured, in the present instance, to one end of the box B.

The interior of the eylinderD is in communication with the cylinder H by a pipe, g, while the cylinder D is similarly in communication with the cylinder H by a pipe, g. I fill the cylinder with water, oil, or other fluid, and I provide each pipe g g with a stand pipe, j, having a checlcvalve, k, in order that the apparatus may be refilled at any time by removing the plate E2 and connecting the standpipesj with a suitable pump, the check-valve preventing the liquid from escaping. Vhen the plate E, for instance, is depressed by a draft animal of an advancing car stepping upon it, under the guidance of the driver, the plunger F is also depressed, as shown in Fig. 2, thereby causing a displacement of the fluid from the cylinder D into the cylinder H, and a corresponding movement of the pistons in the cylinders H H, accompanied by a displacement of the fluid from the cylinder H into the cylinder D. If the plate E is depressed, tlie switch-point a will be moved in the opposite direction and raising the plate E.

I claim as my inventionn 1. The combination of the movable point of a railroad-switch, with plates E E and inten mediate hydraulic mechanism, substantially as set forth.

2. The combination of the movable point of a railroadswitch with plates E E', carrying plungers F F, the hydraulic cylinders D D, and the cylinders H H', having pistons connected together and to the switch-point, substantially as specited.

3. The combination of the movable point with the cylinders H H', carrying pistons and piston-rods, and the block t', attached to both piston-rods and connected to the switch-point, substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

EDWD. SAMUEL.
